Application filed December 30, 1911.

characters are released from a magazine byv escapenients controlled by corresj'ionding finger keys, that they may be assembled tem-1 porarily in line. As certain of the characters, such as e, i, etc., are used more frequently than others, it is the practice to provide in the magazine two channels tor each of these characters, and to provide shitting connections trom a single linger key to deliver the matrices from the two channels alternately, as shown, for example, in Letters Patent of the United States to Mergenthaler No. (i5-8,740, and British Pat cnt No. 19,017 ot 1905. In these mechanisms the shitting of the linger key connections is eiliected at long intervals, usually at the completion et each line oicomposition. Owingto this long interval there is in certain classes oit composition the liability et one channel being` exhausted betere the shift occurs, in which event the operation et the linger key will :tail to deliver a matrix.

rllhe object oit my inif'ention is to provide a simple mechanism by which. the shitting ot' the finger key connections from one escapement to another may be etliected at positive and shorter intervals.

ln all these machines there is a mechanism controlled by a finger key, commonly known as the space key l, tor delivering troni their magazine expansible spacers or justifiers into the composed line, between the word groups of matrices. Ordinarily this mechanism is operated several times during the composition ot each line, generally after every :fourth or fifth character.

My invention consists broadly in the coinbination ot this space-delivering mechanism with the matrix delivering sevices in such .manner as to shift the tinger key connections. This results in the delivery of matrices trom one channel during` the compost.

nel during the composition of the next word, and so on alternately, this frequent changing preventing the possibility ot the inatrices being exhausted in either channel.

it will be manifest to the skilled mechanic after coi'isideration ot this specilication and the a companying drawings, that my invention is susceptible et embodiment in numerous equivalentforms.

ln the drawings i have shown the invention in its preferred forni, as combined with the mechanism of a commercial li/lergen-v thaler machine, ot the present day.

in the drawings, Figure l is a perspective i `ew showing a portieri et the matrix deliv- 'ei-ing mechanism, space delivering mechanism, and finger key connections of a Men genthaler machine with my improvement applied thereto. Figs. 2, 3 and i are side elevations illustrating the device for shifting the connections in their various succes sive positions. Fig. 5 is a vertical cross section on the line 545, Fig. B.

Referring to the drawings; A, r. represent portions of the tra-me work ot the machine; il the inclined channeled magazine in which the mat ices tl, are stored, and trom which they are delivered one at a time by the vibratory escapeinents one tor each channel.

l? are springs which h old the cscapements normally in the positions shown. i

G, G, G2, etc., are vertically guided reeds which litt the rear ends ot the eseapements momentarily to the matrices.

lli is a magazine containing the expansible wedge spacers l, which are delivered. therelfroni one at a time by the pawl J, that they may descend by gravity to the matrix line in course ot' composition. These spacers, and the mechanism for delivering them, may be identical with hose shown in Letters Patent ofthe United States No. ft-36,532, new in con'nnon use, or ot any other suitable construction. The pawl J is actuated by a lever L, pivoted to the main iframe, and, in turn, actuated by a vertical reed M, jointed thereto and eX- tended downward, to be operated by the keyboard connections. rllhe keyboard mechanisni tor operating this reed, and also for operating the escapenient actuating reeds (l, G, etc., is power-driven, and controlled by linger keys. in the torni shown, they are substantially identical with those shown in United States Letters Patent to Dodge No. 530,931, with the exceptions hereinafter noted.

Each of the escapement reeds G, G, etc., actuated by a vertically guided bar N, lying thereunder, and actuated in its turn b y a lifting yoke O, pivoted at one end, and containing a cam 1), which overlies a constantly driven rubber-covered roll Q, this roll extending the entire width of the keyboard, to operate the series of yokes.

Each yoke is held normally in an elevated position, to keep the cam out of contact with the roll, by an angular dog R, pivoted on the main 'frame and controlled by the vertical slide S, connected to a finger key. lVhen the key is actuated it li'ts the bar S, which causes the dog R to release the yoke O, which 'falls and permits the cam P to contact with the roll Q, whereupon the Ytrictional engagement causes the cam to receive a rotary motion from the roll on which it is supported. Owing to the eccentricity of the cam, its rotation causes the yoke O to rise at one end above its original position, lifting the bar N, which in turn lifts the reed G, causing an escapement to be actuated, and a matrix to be released. Vslhen the yoke descends it is arrested in its original. position by the dog R.

1n the ordinary machines the reeds G are continued downward, and each one connected with a cam yoke. In my mecha- -nism the reeds are terminated, as shown,

above the yoke, and the bar N interposed. The lower end of the bar N is mounted in a fixed guide, but the upper end is extended through a horizontally movable guide U, so that the upper end of the bar may be shifted sidewise, that it may operate either one of two reeds, these reeds in turn actuating` the escapemcnts of two channels, which will contain matrices for the same character. lt is the shifting of this guide Vby the spacer mechanism, when it is actuated, that constitutes the leading part of my invention. The connections may be of any character which will Vcause the shifting Yof the bar N when the mechanism is operated to release a spacer from the magazine H. 1n the form shown the mechanism consists simply of a lever V, pivoted at fu, to the main frame, and jointed at its lower end to the guide U, or otherwise connected therewith. At the upper end the lever V is forked, and provided on the inner end of its arms with lips o. To the reed M, which it will be remembered effects the release of the spacers, I pivot two pawls m and m', weighted at the lower end, projecting in opposite directions, and acted upon by springs m2, which normally prevent them from rising above the positions indicated. As the reed M rises the two pawls act alternately on the upper ends of the lever V, causing it to vibrate and shift the guide U and bar N to and fro.

in detail, the operation is as follows :A Assume the reed M to be in the lower position, as shown in Figs. 1 and 2, and the bar N to be in its lett hand position.` When the reed is raised, carrying with it the pawl m, theA end oit the latterA acts beneath the lip on the left side of the lever V; and as the reed and pawl continue their upward movement the pawl, being compelled to turn on its pivot, approaches the horizontal position, as shown in Fig. 3, and pushes the end of the lever V to the left, causing its lower end to shift the guide U and bar N to the right, so that matrices will be released from the right hand channel of the magazine. During this action the right hand pawl m rises inactively above the lever V as shown. wWhen the reed M descends the pawls are again carried downward, and the right hand pawl m engages beneath the lip o, which has been shifted over by the movement of the lever. lVhen the reed M is next raised, to drop the next spacer into the line of matrices, the pawl m/ acting beneath the lip o', and gradually assuming a horizontal position, pushes the upper end of the lever V to the right, causing its lower end to move to the left, thereby shifting the guide U and the bar N to their original positions, so that when a iinger key is actuated matrices will be delivered from the lett hand channel of the magazine. Thus it will be seen that the action of the space key serves to change the delivery ofmatrices from one channel in the magazine to the It will vbe observed that the shiftin g movement is effected by power-driven devices, and that the finger key simply controls the actuation of these devices, there being no additional labor imposed upon the key, or the operator. For rapid composition it is important that all the keys in the keyboard, to operate easily, should oder practically-the same resistance. It one key offers more resistance than another it is found to interfere materially with the speed of composition, causing hesitation on the part of the operator.

1t will be manifest to the skilled mech-anic that the lever and pawls herein shown may be replaced by other equivalent devices for imparting motion from the spacer-releasing mechanism to the devices for shifting the escapement connections without passing beyond the scope of my invention.

Having described my invention, what I claim is:

l. 1n a machine of the class described, the combination of two distinct matrix releasing devices, a single linger key to control them, and a space delivering mechanism adapted to be Operated aft-er the composition of each word and arranged to shift tne connection between the finger key and matrix releasing devices, substantially as described; whereby the key is enabled to actuate the two matrix releasing devices alternately.

2. In ar machine of the class described, the combination of two magazine channels and escapements, two actuating reeds for the escapements, a finger key, connections through which the key controls said escapements one at a time, and a space delivering` mechanism adapted to be operated after the composition of each w'ord and arranged to shift said key connections; whereby the key is caused to deliver matrices from one channel during the composition of one word and from the other channel during,l the composition of the next word, and so on alternately.

3. Two escapements and actuating means therefor comprising a single sliifta-ble connection for operating them alternately, in combination with space delivering devices adapted to be operated after the composition of each Word and arranged to shift said connection each time that a space is delivered.

1. Two escz-tpements to deliver matrices from separate channels, actuating devices therefor, and a single means for controlling them, in combination with a space delivering mechanism adapted to be operated after the composition of each word and which shifts the said controlling means and thus effects the action of said escapements alternately.

5. In a machine of the class described, the combination of manually operable means for delivering matrices from different magazine channels, means for delivering spacers between the composed words, and connections whereby the spacer delivering means will cause the matrix delivering means when operated to deliver matrices from one channel during the composition of one word and from another channel during the composition of a succeeding word.

6. In a machine of the class described, the combination of two matrix escapements, an actuating device therefor, and means for connecting said device with the escapements alternately during the composition of a line, the said means being operated after the composition of each w'ord in the line.

7. In a machine of the class described, finger key mechanism for delivering matrices from two magazine channels, and a finger key mechanism for delivering spacers adapted to be operated after the composition of each word, the latter mechanism arranged to control operative relation of the former to the respective channels, substantially as described.

8. In a machine of the class described, two escapements for delivering matrices, power driven actuating; devices therefor, and a inger key to set them in motion, in combination with power driven mechanism to release spacers from their magazine adapted to b-e operated after the composition of each word, the last named mechanism arranged to shift members of the power driven devices in order to cause the operation of the two escapements one at a time.

In testimony whereof I hereunto set my hand this twenty third day of December, 1911, in the presence of two attesting witnesses.
